Answer:
Probability = 3 / 36 = 1 / 12
Step-by-step explanation:
Probability = Number of favorable outcomes / Total number of outcomes
As there are total of 6 * 6 outcomes, total number of possibilities = 36
According to question,
Possibility of getting the sum of numbers on its faces is 10
So,
( 4, 6 ) will give sum as 10
( 5, 5 ) will give sum as 10 and
( 6, 4 ) will give sum as 10
So ,
Number of favourable outcomes = 3
hence,
Probability = 3 / 36 = 1 / 12
